SUVs are known for their durability, power, and versatility, making them a popular choice for families, adventurers, and everyday drivers alike. But like any vehicle, even the toughest SUV requires proper care to keep running efficiently and avoid major breakdowns. If you want your SUV to remain reliable for years to come, following a few key maintenance habits is necessary. Taking the right steps can help you maximize your vehicle’s lifespan while avoiding common issues that may cut its life short.
Stick to Regular Oil Changes
One of the simplest yet most crucial ways to keep your SUV in top condition is by sticking to a consistent oil change schedule. Oil is the lifeblood of your vehicle’s engine, lubricating its moving parts and preventing overheating. Over time, oil becomes dirty and less effective at reducing friction. Ignoring regular oil changes can lead to engine wear, decreased performance and fuel economy, and even costly engine repairs down the line.
For most SUVs, oil should be changed every 5,000 miles, depending on the type of oil and your driving conditions. If you frequently drive in harsh conditions—such as extreme temperatures, heavy traffic, or off-road terrain—your SUV may need more frequent oil changes. Always consult your owner’s manual or ask your service provider for specific recommendations.
Don’t Forget the Transmission
The transmission is one of the most critical components of any SUV. It ensures smooth shifting between gears and keeps your vehicle running at optimal performance. Yet, it’s often overlooked when it comes to regular maintenance. Keeping your transmission fluid clean and topped up will help prevent overheating and ensure the longevity of this essential system.
Typically, transmission fluid should be changed every 30,000 to 60,000 miles, depending on your SUV’s make and model. Low or dirty fluid can cause issues such as rough shifting, slipping gears, or even transmission failure.
Rotate and Balance Your Tires Regularly
Tires play a significant role in the overall health and performance of your SUV. Uneven wear can affect handling and fuel efficiency and even lead to costly suspension repairs if left unchecked. Rotating your tires regularly helps distribute wear evenly, improving their lifespan and keeping your SUV stable on the road.
A good rule of thumb is to rotate your tires every oil change or every other oil change. Pairing this with regular tire balancing and alignment checks can significantly reduce premature wear and improve your vehicle’s overall safety.
Maintain a Clean Cooling System
Your SUV’s cooling system prevents the engine from overheating by regulating the temperature with coolant. It also circulates coolant through your heater core to heat the cabin in the winter. If the cooling system isn’t functioning properly, the engine can overheat, leading to severe damage and potential failure. Keeping the cooling system clean and ensuring proper coolant levels is crucial for maintaining a healthy engine.
When should you flush the cooling system?
Most experts recommend flushing your cooling system every 40,000 miles or so. However, checking your coolant levels regularly and topping up when necessary can help you avoid overheating problems before they start.
Pay Attention to the Brakes
Your brakes are arguably the most important safety feature in your SUV. Regularly inspecting and maintaining your brakes ensures they’ll work when you need them most. Signs of brake wear—such as squealing, grinding noises, or a longer stopping distance—should never be ignored, as they can lead to dangerous situations and costly repairs.
Brake pads typically need to be replaced every 25,000 to 70,000 miles, depending on your driving habits and the type of pads you have. If you notice any signs of wear or reduced performance, it’s best to have them checked immediately.
Brakes Have Fluid Too
Your SUV's brakes are operated by a hydraulic system which uses brake fluid to transfer the force from the pedal under your foot to the brakes at the wheels. This fluid can absorb moisture from the air and attract contaminants from the outside. Moisture in the brake fluid can boil, causing a soft brake pedal and reduced braking function. Other contaminants can cause premature wear on other braking system components such as the master cylinder, ABS pump and Calipers. Most experts recommend flushing the brake fluid every 2 years or 30,000 miles to keep it moisture and contaminant free.
Keep an Eye on Belts and Hoses
Your SUV’s engine relies on various belts to run the alternator, water pump and power steering and hoses to circulate fluids throughout the vehicle. These components wear out over time, which can lead to bigger problems if not addressed. For instance, a broken serpentine belt can cause your engine to overheat or result in loss of power steering.
It’s a good idea to inspect belts and hoses during regular oil changes. Look for cracks, fraying, or signs of wear. Replacing these parts before they fail can save you from unexpected breakdowns and costly repairs.
Don’t Overload Your SUV
While SUVs are designed to carry heavy loads, there’s still a limit to what they can handle. Overloading your vehicle can put unnecessary strain on the suspension, brakes, and drivetrain, leading to premature wear and possible damage. Always check your SUV’s weight limits—whether for passengers, cargo, or towing—and avoid exceeding them.
Consult your owner’s manual for the recommended weight limits and take note of any additional weight from roof racks or towing trailers. Sticking to these guidelines will prevent undue stress on your SUV’s components.
